> Does the number of mazes created make a difference? Why?

I understand that in some jurisdictions reproducing a small portion of a larger work, then it may constitute fair use. Bullet point 3:

    The amount and substantiality of the portion
    used in relation to the copyrighted work as a whole

http://www.copyright.gov/fls/fl102.html

Of course, this is but one bullet point out of four, and the law is fuzzy, as it should be.

Hadn't thought of that angle. You're right, there may be something in that (though I imagine you could argue each maze is a 'work')

I was more coming from the idea that just because there are lots of them generated surely doesn't mean they fall outsidd the law.
